The stop valve with the improved structure comprises a valve plug, a valve rod and a valve body with an inlet and an outlet; the valve rod and the valve body are in threaded connection, and the outer end of the valve rod extends out of the valve body and the inner end is fixedly connected with the valve plug; the inside of the valve body is provided with a valve seat provided with an upper opening and a lower opening; the upper opening of the valve seat is opposite to the bottom of the valve plug and is communicated with the outlet of the valve body; the lower opening of the valve seat is communicated with the inlet of the valve body; the valve rod and the valve plug are connected into a whole and are made of plastics. The stop valve with the improved structure has the characteristics of simple structure and low manufacturing cost.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of structure improved stop valve.
Background technique
Stop valve is widely used in the supply and drain water system of family, public place, can the snap switch water supply and sewerage pipeline, and make the user easy to use.
Liu Tong stop valve has spool, valve rod and valve body in the market, valve body is stretched out in its valve rod outer end, in valve body, be provided with valve seat, this valve seat has the valve seat opening relative with the spool that is positioned at stem bottom, and valve seat cooperates with spool and constitutes the sealing configuration that above-mentioned valve seat opening is sealed.This directly sealing structure poor-performing by sealing by formation between metal spool and the valve seat, influenced the usability of product, and valve seat in use is subjected to the wearing and tearing of metal spool easily, exist problems such as wear resistance is relatively poor, all adopt metal stop valve cost of production also high simultaneously.
Because valve rod is threaded with spool, drive the switching that spool is controlled stop valve by rotary valve rod, still this control mode is rotated at valve rod and is caused spool to come off out from valve rod easily when excessive.
Summary of the invention
The purpose of this utility model is to exist above-mentioned problem at existing stop valve, and a kind of simple in structure, structure improved stop valve that cost of production is low is provided.
The purpose of this utility model can realize by following technical proposal: a kind of structure improved stop valve, comprise spool, valve rod and have import and the valve body of outlet, described valve rod is threaded with valve body and valve body is stretched out in the outer end of valve rod, inner and spool is connected, valve seat with upper shed and under shed is set in the above-mentioned valve body, the upper shed of this valve seat is relative with the bottom of spool and communicate with the outlet of valve body, the under shed of valve seat communicates with the import of valve body, it is characterized in that described valve rod and spool are connected as a single entity and valve rod and spool all adopt plastic materials to make.
In using this stop valve process, since valve rod and spool be connected as a single entity and valve rod be threaded with valve body, like this by the lifting of rotatable handle, thereby control the unlatching of this stop valve or close, and needn't worry that rotation excessively causes spool to come off out from valve rod with regard to the may command spool.Simultaneously also time saving and energy saving when processing valve rod and spool.Valve rod and spool all adopt plastic materials to make, and have not only saved cost of production, but also can avoid the wearing and tearing between spool and the valve seat, have prolonged the working life of this stop valve.
In above-mentioned structure improved stop valve, described spool is provided with diaphragm seal.
In above-mentioned structure improved stop valve, upper shed place of described valve seat has the annular groove that forms sealing with diaphragm seal.Groove is squeezed at Sealing and does the time spent, the sealing station that can remain valid, thus avoid producing the leakage that the gap causes stop valve because of the sealing surface between valve seat and the spool.
In above-mentioned structure improved stop valve, the described valve body outside is provided with valve gap, and described valve gap is socketed on the valve rod and with valve body and is connected.Can control the stroke of valve rod in valve body by valve gap, make valve rod can in valve body, not come off out.
In above-mentioned structure improved stop valve, be provided with seal ring between described valve gap and the valve rod.Seal ring can prevent that sealing leaks out from valve rod, further strengthens the sealing effect of this stop valve.
In above-mentioned structure improved stop valve, be provided with pad between described seal ring and the valve body.
Compared with prior art, this structure improved stop valve has the following advantages:
1, valve rod and the spool in this structure improved stop valve is connected as a single entity, and just needn't worry when rotary valve rod that like this rotation excessively causes spool to come off out from valve rod.Simultaneously also time saving and energy saving when processing valve rod and spool.
2, valve rod and spool all adopt plastic materials to make, and have not only saved cost of production, but also can avoid the wearing and tearing between spool and the valve seat, have prolonged the working life of this stop valve.
Description of drawings
Fig. 1 is the sectional structure schematic representation of this structure improved stop valve.
Among the figure, 1, valve body; 11, import; 12, outlet; 13, valve seat; 13a, upper shed; 13b, under shed; 13c, groove; 2, spool; 3, valve rod; 4, handle; 5, diaphragm seal; 6, seal ring; 7, pad; 8, valve gap.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this structure improved stop valve comprises spool 2, valve rod 3, handle 4, valve gap 8 and has import 11 and export 12 valve body 1.Valve rod 3 is connected as a single entity with spool 2, and valve rod 3 all adopts plastic materials to make with spool 2 in the present embodiment.
The outer end of valve rod 3 is passed valve gap 8 and is stretched out valve body 1, inner and spool 2 is connected, on valve rod 3, be provided with outside thread, be provided with internal thread in the valve body 1, the valve rod 3 outside threads formation kinematic pair that matches with valve body 1 internal thread, move up or down thereby drive valve rods 3 by Joystick 4 rotation valve rods 3 like this, just drive spool 2 and move up or down, so just can control the unlatching of this stop valve or close.
Valve gap 8 is socketed on the valve rod 3 and with valve body 1 and is threaded, and can control the stroke of valve rod 3 in valve body 1 by valve gap 8, makes valve rod 3 can not come off out in valve body 1.Be provided with seal ring 6 between valve gap 8 and the valve rod 3, seal ring 6 can prevent that sealing leaks out from valve rod 3, further strengthens the sealing effect of this stop valve.Between seal ring 6 and valve body 1, also be provided with pad 7.
